Selective activations

Activating bonds to achieve selective functionalization of complex systems is central to the team’s activities. Our interests in this field are broad and often the fruit of collaborations. We work on methods to activate C(sp2)-Si bonds, on the activation of alkylmagnesium and alkylzinc reagents (C(sp3)–Mg and C(sp3)–Zn) for uses in asymmetric synthesis, on the activation of C–H bonds (ANR CoCaCoLight), and more recently on the activation of N–Si bonds through the implementation of a novel strategy based on aromatic π-acceptor derivatives.
